The massive black hole has been dubbed GW231123. Its unusual size and behavior is challenging scientists' understanding of ...

New gravitational wave findings from the LIGO-Virgo-KAGRA Collaboration report the discovery of the largest black hole merger ...

To date, the collaboration has detected dozens of merger events since its first Nobel Prize-winning discovery. Early detected ...

A new method to analyze gravitational-wave data could transform how we study some of the universe's most extreme events—black ...

It took less than a second for the space observatory hidden in Louisiana woods to detect a black hole that is that is ...

“It’s the most massive [merger] so far,” says Mark Hannam, a physicist at Cardiff University, UK, and part of the LVK ...

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely ...

Gravitational waves spotted by LIGO reveal two black holes, 140 and 100 times the mass of the sun, merged to become a 225 solar mass behemoth.

A physics conference has received a report of the gravitational wave from the heaviest pair of black holes we’ve so far observed merging. The result is larger than theoretical models allow through ...

Black holes with masses below about 60 times that of the Sun – a size small – are created when a star dies. Yet ones between 60 to 130 solar masses have never been seen, with physicists believing that ...
